[Correlation of arterial pressure in the forearm with blood pressure in the ascending aorta].
Forearm blood pressures obtained by auscultation were compared with the data of pressure recording in the ascending aorta during diagnostic catheterization in 243 patients with coronary heart disease, arterial hypertension and some malformations of the heart. With indirect measurement, systolic blood pressure was shown to be sufficiently reliable and to characterize systolic pressure in the ascending aorta with assurance, the pressure in the aorta being slightly less (some 10%) in approximately half the cases. The regression equation for systolic pressure in the ascending aorta against forearm pressure is as follows: Y = 0.96X - 1. Measurement of diastolic pressure in the ascending aorta yields less accuracy, so it is advisable to use two regression equations: (1) Y = 0.98X - 1 for a diastolic pressure of 80 mm Hg or less and (2) Y = 0.85X + 2 for a pressure of greater than 80 mm Hg. Thus, ascending aorta pressure values required for invasive hemodynamic studies may be satisfactorily calculated from the data of blood pressure auscultative measurement.
